Donald Trump went on another of his Twitter rants yesterday railing about the use of unnamed "sources" in news reports about him.

As you can see above, he says "Whenever you see the words 'sources say' in the fake news media, and they don't mention names... it is very possible that those sources don't exist but are made up by fake news writers. #FakeNews is the enemy!"

Now, when he says sources don't exist, is it possible he speaks from first hand experience?
